Privacy Policy
Last updated: 31 August 2026
Tesera Studio OÜ, a private limited company registered in Estonia at Sepapaja tn 6, 15551 Tallinn, Harju Maakond ("Tesera Studio", "we", "us"), designs and publishes mobile apps under its own brand. This policy explains what personal data we collect, why we collect it, and the rights you have under the EU General Data Protection Regulation (GDPR). For the data described here, Tesera Studio is the data controller.
This page covers our website at teserastudio.com and how we handle email. Each app we publish has its own privacy policy describing exactly what that app does with data:
The short version
- We do not sell or rent your personal data.
- Our apps do not require an account, and we do not show ads inside them.
- Optional subscriptions are billed by Apple — we never see your payment details.
- Our apps collect only what they need to work — each app's own policy spells out exactly what that is.
- You can contact us at any time to exercise your privacy rights.
Our website
This website is largely static. You do not need an account to use it. When you visit, our hosting provider (Vercel) records standard server logs — your IP address, browser type, the page requested, and a timestamp. We rely on these logs only to keep the site secure and reliable, on the legal basis of our legitimate interest in operating a safe and stable service. Logs are retained for a short period and then deleted or anonymised. This site does not use advertising or tracking cookies.
Email contact
If you write to us at info@teserastudio.com, we use your message and email address solely to read and reply to you. We do not add you to any mailing list, and we keep the correspondence only for as long as needed to handle your enquiry and any reasonable follow-up.
Data retention
We keep personal data only for as long as it is needed for the purpose it was collected. Server logs are retained briefly and then deleted or anonymised. Analytics and error-reporting data, where an app collects them, are kept only as long as they are useful for understanding and improving our products, and are then deleted or aggregated. Email correspondence is kept for as long as needed to handle your enquiry.
Children
Our website and apps are intended for a general audience and are not directed to children under 13. We do not knowingly collect personal data from children.
Security
We take reasonable technical and organisational measures to protect the data we handle. Where our apps or website exchange data with our servers or service providers, it travels over encrypted connections, and we limit access to the information we hold. No system is perfectly secure, but we work to keep the risk low.
Your rights
Under the GDPR, you may ask us at any time to:
- confirm whether we hold personal data relating to you, and receive a copy of it;
- correct information that is inaccurate or incomplete;
- delete your data, or restrict how we use it;
- object to processing that is based on our legitimate interest;
- receive certain data in a portable format.
Because our apps have no account and we do not link usage data to your identity, there may be cases where we genuinely cannot single out the data relating to you specifically — but we will always help wherever we can. To exercise any of these rights, email info@teserastudio.com. You also have the right to lodge a complaint with the Estonian Data Protection Inspectorate (Andmekaitse Inspektsioon) or your local supervisory authority.
Changes
We will revise this policy as the studio and its apps evolve. The "Last updated" date at the top reflects the current version, and we will post any material changes on this page.
